IMPROVEMENT m- CARRIAGE-AXLES.

The Schedule referred to in these Letters Patent and making part of the'same.

Be a known em .1, wmnm A. LEWIS, ofJoliet, in Will county, and State of Illinois, ln tve invented a new and useful Improvement on a Carriage-Axle; and

I do hereby declare the following to he a full, clear,and exact description of the same, reference being bad to the annexed drawings making apart of thisspccification,in \vhich-- Figure 1 is a longitudinal sectional view of the axle and skein;

Figure a view of the same in the mold; and

Figure 3, a perspective view of the axle, witlrthe' tl |imble'-co're c on the end.

M yinvention consistsin the use ofa hollow tube of metal, a, for the-axle, having the 'skein B cast on the ends, as I shall proceed to explain;

taper at each end, the manner of casting or combining the skein B with the axle is as follows:

A pattern oi'tbc whole combined axle and skein be-' ing constructed of wood, the same is molded in the sand 1). The same being removed, the hollow tube or axle a, is-put in its place, asshown in fig. 2, and the shown in said figure.

To prevent themolten metal from runuingin to fill' the hollow tube or axle (l, I use a thimble-core, c, of

i I I y The axle a passes in the skein B to near the mid: dle, as shown in figs. 1 and 2 so as to give strength to the axle. V i

It is readily observed that the axle and skein are hollow the entire length, which makes the whole very light and strong.

I'do not claim the idea of a compound axle as new and original, but desire to confine myself to the mec-hanical construction and combination described, so that what I consider I have invented is the cornbination of the three parts described in such a manner as I have set forth, so the whole will be hollow the entire length. The pattern by which the whole is cast has the necessary gather, so the pendent spokes will stand in any position required, and the same pattern being used for each axle, the same will cause the wheels to track exactly.

Having thus described my invention,

What I claim as new, and desire to secure by Iletters Patent, is as follows:

Claim.

' The combination of the hollow axle 11-,skein B, and

thimble-corc c, constructed, operating, and arranged as and for the purposes set forth.
